He's really good for not-so-techy things, but he's an old bitter man that hates wasting time. The car was checked over by RCTS as well, and they thought it was solid. I don't know, I've taken the car for three drives now far over an hour and haven't had any heating issues. I burped the cooling system and topped it up with some distilled water too and it seems okay. Again, checked both fluids and bought test strips and neither show signs of a BHG. One thing I have noticed is the hesitation is getting worse... Seems like it's not getting ignition under load, and it's starting to do it at w.o.t. in ALL rpm's, boost or not. I just changed the plugs not too long ago for some ngk iridium's, I think I'm going to do the wires today. Definitely thinking my problems are ignition related.
